摘要

为了优化液晶类微管激光器的性能, 本文研究了偶氮染料掺杂聚合物分散液晶微管激光器出射激光的性能及光控性。通过在不同纤芯直径的玻璃毛细管中制备掺杂偶氮染料的PDLC, 并分别测量这些样品的随机激光阈值。增加紫外线照射强度, 测量随机激光的光谱。实验结果表明,不同芯径毛细管样品(100 μm, 300 μm, 500 μm)的随机激光阈值测量为11.8 μJ/脉冲, 8.6 μJ/脉冲和13.2 μJ/脉冲。实验结果还表明, 随着紫外线照射强度的增加(从0 mW/cm2 增加到150 mW/cm2), 随机激光强度逐渐减小, 光谱的半高宽变宽。随机激光在光学调谐过程中在不同偏振方向的紫外光束下显示出相似的特性。该工作验证了在圆柱形约束结构中制造微型激光器件的可能性, 并扩展了PDLC的应用范围。

Abstract

This study demonstrated the optically tunable random lasing from azo-dye-doped polymer dispersed liquid crystal (PDLC) in capillary tubes, in order to expand new applications for this device. The azo-dye-doped PDLC was prepared in glass capillaries with different core diameters, and the random lasing thresholds of these samples were measured respectively. The spectra of random lasers were measured with increasing the intensity of ultraviolet radiation. The experimental results show that the random laser threshold measurements of different core diameter capillary samples (100 μm, 300 μm, 500 μm) are 11.8 μJ/pulse, 8.6 μJ/pulse and 13.2 μJ/pulse. The experimental results also show that as the intensity of ultraviolet radiation increases (from 0 mW/cm2 to 150 mW/cm2), the random laser intensity decreases gradually, and the FWHM of the spectrum becomes wider. And the random lasing showed similar properties under the UV beam with different polarized directions during the optical tuning process. Our work verifies the possibility to fabricate miniature laser devices in cylindrical confinement structures, and extends the application scope of PDLC.
